* rt_getifa() is only needed for routing commands submited by userland.mpi2017-07-241-2/+123
| | | | | | | | So rename it to rtm_getifa(), move it where it belongs and stop calling it from rtrequest(9). Route entries created by the kernel must always specify the corresponding `ifa'. ok claudio@
* Both PF_ROUTE and PF_KEY need to start to take care of their own PCB listclaudio2017-07-031-55/+58
| | | | | | | to simplify the locking of those lists. For now move the LIST_ENTRY from rawcb into routecb and in the pfkey case a new keycb. Do some cleanup and renaming in the pfkey code but more to come. OK bluhm@ mpi@
* Assert that the corresponding socket is locked when manipulating socketmpi2017-06-261-7/+8
| | | | | | | | | | | | | | | | buffers. This is one step towards unlocking TCP input path. Note that all the functions asserting for the socket lock are not necessarilly MP-safe. All the fields of 'struct socket' aren't protected. Introduce a new kernel-only kqueue hint, NOTE_SUBMIT, to be able to tell when a filter needs to lock the underlying data structures. Logic and name taken from NetBSD. Tested by Hrvoje Popovski. ok claudio@, bluhm@, mikeb@

* Move PRU_ATTACH out of the pr_usrreq functions into pr_attach.claudio2017-03-131-41/+47
| | | | | | | Attach is quite a different thing to the other PRU functions and this should make locking a bit simpler. This also removes the ugly hack on how proto was passed to the attach function. OK bluhm@ and mpi@ on a previous version

* Do not grab the NET_LOCK() for routing sockets operations.mpi2017-03-071-3/+11
| | | | | | | | The only function that need the lock is rtm_output() as it messes with the routing table. So grab the lock there since it is safe to sleep in a process context. ok bluhm@

| | | | | | | | | | this lets pflogd run again. rename if_data() to if_getdata() while here to make grepping for things less noisy. reported by jsg@ worked through with deraadt@
* merge the ifnet and ifqueue stats together when userland wants them.dlg2017-01-231-3/+3
| | | | | | | | | | | a new if_data() function takes a pointer to ifnet and merges its if_data and ifq statistics. it takes the ifq mutex around the reads of the ifq stats so they get a consistent copy. the ifnet and ifq stats are merged because some parts of the stack still update the ifnet counters. ok visa@ (on an earlier diff) mpi@ claudio@

| | | | | | | | | | softnet assert failures. It is better to place the lock into net_sysctl() where all the protocol sysctls are called via pr_sysctl. As calling sysctl(2) is in the slow path, doing fine grained locking has no benefit. Many sysctl cases copy out a struct. Having a lock around that keeps the struct consistent. Put assertions in the protocol sysctls that need it. OK mpi@

| | | | | | | | | | | of the network stack that are not yet ready to be executed in parallel or where new sleeping points are not possible. This first pass replace all the entry points leading to ip_output(). This is done to not introduce new sleeping points when trying to acquire ART's write lock, needed when a new L2 entry is created via the RT_RESOLVE. Inputs from and ok bluhm@, ok dlg@
